Description

Technical Field

[0001] The utility model relates to the technical field of flat cables, in particular to a high-voltage-resistant and tear-resistant flat wire. Background Art

[0002] A flat cable or ribbon cable is a flat wire formed by combining many wires together. This kind of cable has low cost, light weight, strong toughness, and is easy to use in both large and small equipment. However, the general flat cable has limited voltage resistance and is easily damaged by pressure.

[0003] For example, Chinese Patent CN214123533U discloses a flat cable, which includes a filling layer. A plurality of copper conductors are inserted into the filling layer, and the plurality of copper conductors are arranged side by side in a straight line. The outer wall of the copper conductor is wrapped with an insulating layer, the outer wall of the insulating layer is tightly wrapped with a second wire mesh, and the outer wall of the second wire mesh is closely attached to the filling layer. The outer wall of the filling layer is tightly wrapped with a first wire mesh. By filling the groove with a coating made of aluminum hydroxide material, it can react to achieve flame retardancy when the cable withstands a high temperature that can melt high-temperature rubber, greatly increasing the flame retardancy performance. Through the cooperation of the asbestos mesh, the first wire mesh and the second wire mesh, heat transfer can be carried out when the cable locally withstands high temperature, avoiding the local temperature reaching the combustion temperature, and it has good heat resistance, but its compressive strength is limited and it is easily damaged by external extrusion.
